Blossom end rot, one of the most prevalent tomato problems. Usual cause is a water imbalance such as the soil is too wet, too dry. It is critical to monitor your watering and maintain consistent levels of moisture during the growing season. Calcium moves thru the plant with an ample and consistent water supply. So an inadequate uptake of calcium from the soil to leaves and fruit will cause the end rot. Keep in mind that the plant will require more water when it is hot and dry. With consistent watering the plant should be able to take up enough calcium from the soil.
Have you had a soil test done? This would confirm whether your soil is calcium deficient or not. Generally speaking most soils contain adequate amounts of calcium. Highly recommend a soil test prior to adding any nutrients to soil.
